CARL F. GLOCKER, OF ALBANY, NEW YORK.V

GASMBURNER.

SPECIFICATION forming part of Letters Patent No. 722,226, dated March 10, 1903.

Application filed May 16, 1901.

To a/ZZ whom, t muy concern:

Be it known that I, CARL F. GLOCKER, a citizen of the United States, residing at Albany, in the county of Albany and State ot' New York, have invented a new and useful Improvement in Gas-Burners, ot which the following is a specification.

This invention relates generally to gasburners, and more particularly to one adapted for use in connection with the incandescent gas-lamps now in use, in which a mantle of a refractory material is employed.

The object of the invention is to provide a novel means for regulating the flow of gas t0 the burner and also a novel means for supplying gas to the pilot-tube for the purpose of igniting the pure gas prior to the ignition of the mixed air and gas.

With these objects in view the invention consists in the peculiar construction of the various parts and in their novel combination or arrangement, all of which will be fully described hereinafter and pointed out in the claims.

In the drawings forming part of this specification, Figure 1 is a view showing the practical application of my invention. Fig. 2 is a verticalsectional View. Fig. 3 is a section on the line 3 3 of Fig. 2. Fig. 4 is a section on the line 4E 4; of Fig. 3. Fig. 5 is a view showing the several parts detached. Fig. G is a sectional View showing a slight modification. Fig. 7 is a section on the line 7 7 of Fig. Fig. Sis a view taken on the same section, the parts being adjusted to permit an increased flow of gas. Fig. 9 is a view of the parts detached with the exception of the turn-plug. Fig. 10 is a perspective View of the said plug.

In carrying out my invention I employ a casing A, which is so constructed at its lower end that it can be iitted upon any of the chandelier or bracket arms now in use. This casing A has a vertical bore or passage-way A', through which gaslis intended to pass, and the casing is also formed with a horizontal bore A2, in which is located the turn-plug B, said plug having a passage-way B', adapted to register with the passage-way A' for the purpose of feeding gas to the burner. This turn-plug is secured in the usual manner and is operated by means of the handle or lever C, rigidly attached to one end. The casing A is also Serial No. 60,569. (No model.)

provided with a supplemental passage A3 of a smaller diameter than the passage A', and

the turn-plug B is also formed with asupplemental passage B3, which is adapted to register with the passage A3 and permit the fiow through the casing, the passage of such gas through the turnplug being regulated by means of a needle-Valve B2, screwed into the end of the turn-plug, as most clearly shown in Fig. 2. A pilot-tube D is screwed into the casing A and communicates with the supplemental passage A3, said pilot-tube eX- tending upwardly a considerable distance and terminating in the center of the screen E.

said screen being stretched across the cap F of the burner, said cap having a downwardlyextending tubular portion F', which fits over the burner-tube G, and between the burnertube G and the casing A is the mixing-chamber H, ordinarily termed the shutter, said chamber having apertures H' produced in the sides and through which air passes into the tube G, commingling with the gas prior to its ignition upon the top of the screen E. As before stated, the pilot-tube is to conduct the unmixed gas to the top of the screen, so that it can be ignited and produce a smaller flame for the purpose of igniting the mixed air and gas, thereby avoiding the usual explosion and shock which occurs when the incandescent gas-burners of the ordinary construction are lighted.

In order to regulate the flow of gas to the mixing-chamber and burner, I arrange a conical-shaped plug I at the end of the-passageway A', thereby vforcing the gas out laterally through the opening K, and upon the upper threaded portion L of the casing A is screwed a thimble M, having a central aperture M', through which the apex of the conical-shaped plug I is adapted to pass. This thimble M Iits over the conical plug, and consequently the openings K, and controls the passage of the gas, it being understood that the gas may be shut off entirely by turning the thimble down, so that the apex of the plug will seat lfirmly into the aperture M' and close the same, and by turning the thimble so as to elevate the upper end slightly the iiow of gas through the aperture M can be readily regulated, and in order to operate the thimble from the exterior I attach a screw M2 there- IOO LII

to, the shank of Which travels in the horizontal slot H2, produced in the shutter, said shutter being screwed to the casing A, as most clearly shown in Fig. 2.

The cap F of the burners is formed with inwardly-projectingshoulders F2, upon which the spreader N rests, said spreader comprising a series of fingers N and the depending tubular portion N2, Which iits upon the pilottube D, said pilot-tube serving to hold the spreader in its proper central position.

By means of the conical plug I and the vertical tubular perforated thimble M, I am enabled to regulate the How of gas to the burner, and by means of the needle-valve B2, I am enabled to regulate the flow of gas to the pilottube, and by the employment of this pilottube I am enabled to conducta light, asmall quantity of pure gas at the top of the burner in advance of the ignition of the mixed air and gas upon the screen of the burner.

In Fig. 6 I have shown a very slight modi- Iication in my improved burner. In said iigure the shutter, the burner-tube, the cap, and spreader are identical. The turn-plug is also constructed with a main passage-way and also With a supplemental passage-Way, and a regulating needle-valve is also employed. The pilottube, however, instead of being arranged at one side of the casing, as shown at Fig. 2, is arranged directly in the center and is formed With an enlargement O, having upwardly-tapering recesses O', through which the gas escapes, a regulating-sleeve P being used in connection with the recessed enlargement O instead of the thimble M, the operation of the sleeve P and the recessed enlarge- Vment O being exactly the same as the conical hood and apertured sleeve, and the sleeve is slotted to permit the movement of the operating screw or handle. In Fig. '7 I have shown the sleeve P adjusted to permit a small quantity of gas to be fed to the burner, While in Fig. 8 I have shown the sleeve adjusted to pass a much larger quantity of gas, it being understood that by turning the sleeve down a greater quantity of gas is permitted to escape, owing to the fact that the recesses O' are broader at their lower ends than at their upper ends. It Will therefore be noted that the operation of the mechanism shown in Figs. 6, 7, 8, and 9 is identically the same as the operation of the mechanism illustrated in Figs. l to 5, inclusive.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

l. A gas-burner comprising a case having main and supplemental gas-passages, a turnplug arranged Within the casing and having main and supplemental gas-passages, a needle-valve arranged in the turn-plug to regulate the ioW of gas through the supplemental gas-passage, a pilot-tube communicating with Ythe supplemental gas-passage, and a burnersleeve arranged upon the casing and adapted' to regulate the flow of gas therefrom, the shutter arranged upon the casing, the burner-tube and the cap arranged as described.

3. A gas-burner comprising a casing having main and supplemental passages, a turn-plug having main and supplemental passages, the shutter, the burner-tube, the cap and the spreader, the needle-Valve for regulating the passage of gas through the supplemental gaspassage, a threaded sleeve having a central opening adapted to regulate the passage of gas from the main gas-passage to the shutter, an operating screw or handle attached to the regulating-sleeve Working through a slot produced in the side of the shutter, substantially as shown and described.
